When the battle begins, you are in a force field arena. Try not to hit the force field, or you will get hurt. Enemies from outside the force field will be throwing green gas grenades at you. If you get dizzy from the green gas, rotate the Left Analog-stick to regain control of Wolverine. Juggernaut has a special move where he creates shockwaves by slamming his hands together. Try to get as far away from him when he does this to avoid getting hurt. Juggernaut is invincible while running; make him run into the the force field "corners". The best way to do this is to stand at one of the "corners" opposite from where Juggernaut is standing. When you make Juggernaut hit one of the "corners", he will get shocked, get thrown into the middle of the arena, and will become dizzy. Run up to him and hit him a few times. When you see the "Strike" message, strike him to make him lose health. Do this at least three or four times. After you strike Juggernaut several times, you will see Colloso jump over the force field fence. Run up to him and press Strike to make him throw Wolverine at Juggernaut to defeat him.

In the first part, lure him into the actual poles of the fence. When he flies away and lands dazed, attack him from side and watch for the "Strike" message to appear. Later when he starts jumping, jump to avoid the shockwave and try to get him to jump into the electric beams. He is weak after he jumps. He will stand and send a series of shockwaves. Also jump over these. If he is on one side of the "ring", run to the other side to avoid them. Watch out for the gas. When his health is gone, you must to finish him with a strike. Note: Beware of gas and watch your bar for your sickness level.
